Censuses in the USA and statistics of immigration from Poland – methodological-historical perspective
Censuses of population and housing in the United States are of particular interest to experts in many disciplines – in addition to statisticians, also to demographers, political scientists, sociologists, historians, and even psychologists and anthropologists. This is so not only because of the long history of US censuses (the first census in the US was carried out in 1790) or methodological innovations, but due to immigration responsible for the dynamic population growth, and to the specific purpose of the census, which is ensuring the proportional (according to the numer of inhabitants) distribution of seats in the lower chamber of Congress and federal funds (apportionment), guaranteed by the US Constitution. The heterogeneity of the American society, both in the racial-ethnic and religious-cultural sense, in addition to the above considerations, raise questions about the purposes of those changes and directions for improvement in subsequent censuses. The aim of the article is to present the problems and challenges related to censuses in the USA. The paper focuses on methodological and operational solutions that can be implemented thanks to several improvements, including the progress in the fields of statistics and technology. The paper also discusses the issues of credibility of the census data, based on the example of immigration from Poland and the Polish diaspora in the USA.
